- Make a complite new Map with TERRITORY.map should be a strategic map i.e. Victoria,World of battles (Grand strategy) and etc. and there alliances can go to war for territories,which will generate wealth,resources or maybe even new troops,that can be recruited in specifig territory,also u can store troops there,build fort with ur alliance and so on,others thing i'll leave to your creative minds :P PS: create a new button,so u can switch between normal map and alliance wars.
- Detection units for each race,so they could detect elves and future invisible units
- Assassins/Rogue for human with hide skill
- Rhino riders for orcs,they are slow,but hace chare skill,so they charge forward and knock down everything in thier path and damaging it,but they also receive damage each unit they hit.
